What is the initial movement speed in ATC Bypass mode?

In ATC (Automatic Train Control) Bypass mode, the initial movement speed is restricted speed. This mode is designed to allow train operations under specific conditions where automatic speed control is not active, typically due to a system malfunction or when maintenance work is being conducted.

Restricted speed is a carefully defined speed limit that ensures the train can stop within a distance that is clearly visible to the engineer. This is crucial in ensuring safety when the automatic controls are bypassed, as it provides a margin for stopping in case of any unexpected obstacles or situations on the track.

Understanding the distinction between restricted speed and normal, high, and emergency speeds is essential for train engineers, as these other speeds may not incorporate the necessary safety precautions required under ATC Bypass mode. Normal speed allows for standard operations under normal circumstances, while high speed indicates maximum velocity allowed in operational conditions. Emergency speed, on the other hand, is a specific protocol for situations requiring immediate braking or safety measures.
